Recovery Properties

Replication Delay

Data replication can be delayed in the Replica server spool before sending it to this Replica. This is useful against data corruption or viruses. It enables stopping replication before corrupted or infected data is written to the Replica.

Delay Interval (min)

Enter the number of minutes of the replication delay.

Data Rewind

Keeps undo information needed to recover data from a certain action or point in time. It is useful in cases in which corrupted data on the Master was replicated to the Replica, and you want to restore the data to its previous state before the corruption occurred. Data Rewind is enabled for online replication only.

Retention Period (min)

I/O operations are recorded in the Rewind journal for this number of minutes. Then, they are discarded in first-in-first-out order.

Max Disk Size (MB)

Enter the maximum disk space allocated for the Rewind journal. Once this size is reached, old records are discarded in FIFO order.
